IMPROVEMENT IN CHAIN-PUMPS.

Specification forming part of Letters Patent No. 35,499, dated June 10,18o?.

To all whom it may concern.-

`Be it known that I, ALBERT GREEN BRAD- FORD, residing at present atFreeport, in the county of Stephenson, in the State of Illinois, haveinvented an Improvement in the Mode of Constructing GhainPumps, and I dohereby declare that the following is afull and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon.

The nature of my invention consists in pro viding a succession of smallbuckets connected together, so as to form an Vendless series of bucketsfor the purpose of velevating Water or other fluids with less frictionand greater eX- pedition than with the old chain and buttons.

To enable others skilled in the art to make and use my invention,I willproceed to describe its construction and operation.

I construct my buckets A i-n the form of a cylinder having handles ateach end with a loop or hole in the middle of it, as shown at B B,Figure 1, for the purpose of receiving the connecting-rings, asshown atc c, Fig l.

The improvement `consists in substitutingfa chain of small buckets of aconvenient size, fastened togetherlby means herein described,

`for the common chain and buttons and for the chain 0f small bucketsmore Water will be lifted in less time; or I make the handles with -anangle in the middle to prevent the rings c c, Fig. 2, from slipping fromthe center Aof the handle, where they are connected together;

but this I do not claim.

I make my buckets of iron or any other suitable met-al, or ofgutta-percha, india-rubber, or wood.

vIn order to have no waste of water, the pump can be constructed with atrough of sufiicient width and length to pass under and beyond the chainof buckets, with a small aperture on eachside in the bottom of the sameto allow the buckets to pass through in ascending on the one side .anddescending on the other. To prevent freez- ALBERT GREEN BRADFORD.
